But in its bid to recruit higher-level teaching assistants (HLTAs) specialising in maths and science, the Training and Development Agency for Schools has taken more extreme measures. The agency has drafted in Jo Salter, Britain's first female RAF fast jet pilot and a motivational speaker, to get ordinary teaching assistants "fired up" about becoming HLTAs.
There are striking similarities between the life of a teaching assistant and that of a Tornado fighter pilot in control of pound;25 million worth of screaming metal.
Ms Salter's publicity literature describes her as "combat ready", presumably a key talent for anyone bracing to face Year 8 physics.
It goes on to explain that the former member of the 617 Dambusters squadron has "lightning fast" reflexes. Her other talents are listed as "boundless energy, never-failing humour, compassion and understanding". Oh, and she's a mum.
We are sure she will succeed in her latest recruitment mission. As someone used to cruising above 30,000 feet, she will also bring new meaning to the "higher level" bit of the job title.
